"The successor to our high flow dual hole transfer port;  we have managed to optimize and even enlarge the air passage in this new version 2 of our High Flow V2 Dual Hole Transfer port. The V-shaped transfer opening makes sure you will have the maximum and smoothest air passage area. The middle support bridge divides the transfer port into a dual hole port. This middle bridge makes sure the pellet or slug nose cannot fall into the enlarged transfer port hole, but will be guided smoothly by the middle bridge into the barrel.

This dual hole transfer port has much larger air passage area compared to the oem port for maximum performance. 

 

Please note:

Any modification done to the airflow of your rifle, will affect the entire setup and performance, you might need to re-adjust the settings of your rifle again to get the best posible performance.
Due the already huge increase of the airflow opening, the .177 dual hole model is not V-shaped


We have modified the o-ring groove dimensions and and locating notch of the transferport to be compatible with both the newest rifles as well as the older versions from FX.
Before tightening the grubscrew that holds the barrel in the breech, make sure the barrel is adjusted properly so the magazine slides in and out smoothly.
